IMPROVEMENT IN TUGfLlNKS.

Specification forming partof Letters Patent N0.'22l,l81, dated November4, 1879; application filed September 5, 1879.`

To all whom it may concern:

Beit known that I, HENRY J. MonnLAND, of Pittsburg, in the county ofAllegheny, Sta-te of Pennsylvania, have invented a certain new anduseful Improvement in Tug-Links; and`I do hereby declare that thefollowing is a full and exact description thereof, reference being hadto the accompanying drawings, and to the letters of reference markedthereon.

parts, in contradistinction to encircling a tug-- link composed of twodetachable parts with a spring, as in my former patent above referredto, the whole being so arranged that when the draft is brought to bearupon the tug the two sections draw in opposite directions in proportionto the force brought to bear upon the spiral spring. c

To enable others 'skilled in the art to make and use my invention, Iwill proceed to dcscribe its construction and operation.

In the accompanying drawings, which form part of my specification,Figure l is a. side elevation of my improvement. Fig. 2 is alongitudinal section of the same. Fi g. 3 is a transverse section atline y of Fig. 2.

In the drawings, A represents the female portion of the cylinder; B, themale portion, in which is placed the spiral spring (l.

D represents the gib and key for holding the spring in place. c is awasher placed within the cylinder at one end of the spiral spring, andis used for the purpose of keeping out mud or slush, and forming afbearing for the inclosed spring.

The inner end of the section B is united by a transverse piece, f, andthe part A, at the point of union, is held in position with relation tothe part B by the beveled edges indicated at g. The openings or loops hare for attaching the tug-link to the vehicle and traces.

I am aware that aeylindrical shell inclosin g two flat draft-links,which in turn inclose a spring, is old, and such I do not wish to beunderstood as claiming, broadly, as my inven tion; nor do I wish to beunderstood as claiming, broadly, anything shown anddescribed in myformer patent, before referred to.

kBy my present construction of tug-link, i

.while the spring is inclosed in a cylinder, it can be readily removedand replaced, or a new one substituted therefor, in consequence of thecylinder being made in two detachable parts.

Having thus described my improvement, what I claim, is

1. A tug-link consisting of a cylinder constructed in two detachableparts, A and B,

inclosing a spiral spring, C, held in place through the medium of a giband key, said parts operating substantially as herein described, and forthe purpose set forth.

2. A tug-link consisting of a cylinder con structed in two detachableparts, A and B, inclosing a spiral spring held in position through themedium of a gib and key combined with a washer, e, substantially asherein described, and for the purpose set forth.
